Abstract

Organosilsesquioxanes having at least one mesogenic side group and processes for their preparation, which comprise reacting organosilsesquioxanes having at least one Si-bonded hydrogen atom with chiral or achiral mesogenic compounds containing an aliphatic multiple bond. The organosilsesquioxanes of the invention are useful, for example, in optoelectronics, non-linear optics, communications technology, computer technology, displays, optical switches, information stores and integrated circuits as well as for medical uses.
